FAQs
The 85100A1811SW50 is part of the Souriau 851 series MIL-DTL-26482 family and uses a square flange receptacle with a straight backshell adaptor and 1/3 bayonet coupling. It is designed to mate with compatible MIL-DTL-26482 plugs and connectors within the same series, providing consistent geometry, alignment, and electrical continuity for harness assemblies in aerospace, defense, and industrial systems.
This receptacle features 11 solder cup contacts in an 11-cavity layout, aluminium shell size 18, cadmium plating, and delivers with a straight backshell adaptor and W orientation. The overall length is 41 mm, with 33.7 mm width and height. Operating temperature ranges from -40 °C to 125 °C, and the unit weighs approximately 38.1 g, supporting reliable performance in harsh environments.
Yes. The part is MIL-DTL-26482 SI qualified, designed for high-reliability interconnects in aerospace and defense environments. Its aluminium shell, cadmium plating, and 11 solder cup contacts provide robust performance under vibration, temperature extremes, and corrosion-prone conditions typical of airborne and ground-based military equipment.
Key considerations include MIL-DTL-26482 SI qualification for system reliability and REACH compliance to meet environmental regulations. Cadmium plating offers corrosion resistance but may require downstream recycling or compliance review per program requirements. When selecting, confirm downstream harness compatibility and ensure correct mating plugs from the Souriau 851 series are used.
The 85100A1811SW50 features a W-oriented, square flange receptacle with a straight backshell adaptor and 1/3 bayonet coupling. The footprint aligns with standard 851 series sockets, simplifying installation in constrained equipment bays and ensuring consistent alignment across assemblies. This minimizes mis-mating risk and accelerates field servicing.
